In October, the market of cis polybutadiene rubber was weak and declined. According to the data monitoring of the business community, the price of cis polybutadiene rubber was 12210 yuan/ton as of October 30, down 6.22% from 13020 yuan/ton at the beginning of the month. Although the downstream commencement in Jinjiu peak season is not as good as that in previous years, it has slightly increased compared with the early stage, which has a certain need for support for cis-1,4-polybutadiene rubber. In addition, at the beginning of the month, the raw material price rose significantly, which promoted the rise of cis polybutadiene rubber on the cost side; In the middle of the month, some enterprises started to shut down their Shunding plants and reduce the load, reducing the pressure on the supply side of Shunding, and supporting the Shunding market; At the end of the month, the price of raw materials fell sharply, and the rise of cis-1,4-polybutadiene rubber was limited by the drag of cost.

Supply side: In October, the construction of cis-1,4-polybutadiene rubber was still at a high level, and the pressure on the supply side of cis-1,4-polybutadiene rubber remained unchanged. Under the pressure of supply side, cis-1,4-polybutadiene rubber is weak.

Cost: butadiene prices fell sharply in October, and the cost was not supported by cis-1,4-polybutadiene rubber. According to the monitoring of the business community, as of October 31, the price of butadiene was 7603 yuan/ton, down 8.43% from 8303 yuan/ton at the beginning of the month.

In October, the natural rubber market went down all the way, and the substitution advantage of cis-1,4-polybutadiene rubber was no longer, which had a negative impact on cis-1,4-polybutadiene rubber. As of October 31, the price was 11170 yuan/ton, down 9.26% from 12310 yuan/ton at the beginning of the month.

Demand side: The commencement of tires in major downstream consumer industries in October was slightly lower than that in September. According to the business community, in mid October, the commencement of all steel tires in Shandong was around 5.2%, and the commencement of semi steel tires was 6.5% (the commencement load in September was 5.9%, and 6.3% respectively), which had weak support for styrene butadiene rubber.

Future market forecast: according to the analysts of the business community, the supply side of cis polybutadiene rubber remained loose in October, and the pressure on cis polybutadiene rubber continued to increase in the later period. In addition, the cost side was lower, and the demand side was weak. It is expected that cis polybutadiene rubber will continue to decline in November.
